A standard walker (E0130, E0135, E0141, E0143) and related accessories are covered if both of the following criteria are met:

1) It is prescribed by a physician for a patient with a medical condition impairing ambulation and there is a potential for ambulation; and

2) There is a need for greater stability and security than provided by a cane or crutches.

A heavy duty walker (E0148, E0149) is covered for patients who meet coverage criteria for a standard walker and who weigh more than 300 pounds.

A heavy duty, multiple braking system, variable wheel resistance walker (E0147) is covered for patients who meet coverage criteria for a standard walker and who are unable to use a standard walker due to a severe neurologic disorder or other condition causing the restricted use of one hand. Obesity, by itself, is not a sufficient reason for an E0147 walker.
